Nigel,
Thank you for your response. I tried the no_root_squash, which certainly made sense, but to no avail. I'm going to try some of the other methods suggested, but I'm still wondering if there is something else along these lines.
Thank you again.

Subject: Re: Maintaining Ownership When Copying Files and Directories
You probably need to set the no_root_squash on the export.
By default root permission is not maintained across NFS mounts. This is
to prevent an administrator on the NFS client reading files to which
they should not have access, writing where they should not be able to
and, worst of all, planting suid root executables to run on the server.
However, if you administer both client and server you can override this
and give yourself root access to the server's files on the client using
the no_root_squash in the export options.
Be very careful unless you are the only person with root access to all
the NFS hosts.
